Dear All
We are getting following error after 15 scf cycle.
'LAPW2' semicore band ranges too large, ghostband?
Structure file attached with mail and initialization done with these
parameters (VXC =13 PBE, RKMAX 7.0, K-point in full BZ 100)
Thanks and Regards

Dear professor Laurence:
Thank you for your reply. I used MSR1a mode in my calculation. BTW, I didn't
know that there's a difference in the force convergence between PORT and
MSR1a. If possible, could you tell me about it as well?
Best regards,
Wenhao
There is a difference between the two. Both use the TOLF number in
case.inM, see 8.13.3 in the UG. Port stops when the forces on all the atoms
are smaller than this. MSR1a stops when all the pseudo-forces are less than
this for three consecutive scf iterations. With MSR1a the script may change
Probably none of the methods.
The interlayer binding of graphele is maily due to van der Waals forces
and common GGA functionals do not provide any reasonable binding.
LDA is probably overbinding and a weak GGA (WC ?) may give you some
small binding. Even double minima may occur, ...
It may or may not be related to the problem, but it looks like after it
prints the line
